Battery Case for iPhone 8plus/7plus/6 Plus/6s Plus, Upgraded [8500mAh] Protective Portable Charging Case Rechargeable Extended Battery Pack for Apple iPhone 8plus/7plus/6 Plus/6s Plus(5.5') - Black Review:


The highest capacity I've seen on a battery case is the first thing I like about this case, in addition to the fact that it charges using a lightning wire (8,500mAh). On the iPhone 7 Plus I'm using this on, that's almost three times the battery life. I've used a variety of other charging cases, such as the Mophie, and I dislike having to carry about a few extra wires. I no longer have to! I don't need to carry a power bank either because of how large the capacity of this charging case is. The fact that the shape is the same on the top and bottom makes it appear to be just like any other case, which is another benefit. Like most charging cases, this one doesn't include an extra portion on the back.The iPhone's charging port's lightning tip will be susceptible to fracture, which will be the only issue, in my opinion. This can become an issue if you frequently take your phone in and out of the case. There is a picture on the inside of the case reminding you not to slide your iPhone at a sharp angle. Time will only tell.



Battery Case for iPhone 6s Plus/ 6 Plus/ 7 Plus/ 8 Plus 8500mAh,Portable Charger Case Rechargeable Charging Case, Battery Pack Cover Power Bank for 6s Plus/ 7 Plus/ 8 Plus (5.5 inch) Review:


I adore this case since it allows me to easily go two days without charging my phone and probably longer if I need to, but I haven't really paid attention to it lately because of how hectic my schedule has been.When I'm working outside, sometimes just moving around may cause it to accidently start charging in my pocket, but that is really not a problem beyond my control.Even though it works perfectly for me because I charge it once and then leave it alone while sleeping or working nearby, the female adaptor is just "ever so slightly" loose, so I can see how it would be a problem for others who continuously charge their phones. That the phone can and will be charged initially while within the case is great.It is a little weighty and big, but given the 8500mAh capacity, I wasn't surprised.This case is now my first choice if you're searching for a powerful battery for extended periods without electricity yet still require your phone.



Swaller Battery Case for iPhone 8 Plus 7 Plus, 5000mAh Ultra-Slim Charger Case with Full Body Protection, Extend 120% Battery Life, Portable Charging Case Compatible with iPhone 8 Plus 7 Plus(Black) Review:


The Swaller battery case is only compatible with the iPhone 7 Plus or iPhone 8 Plus, but what I enjoy most about it is that it is black and feels really sturdy. The fact that all the ports have been precisely carved out makes it incredibly accessible. If you lay your phone face down, the upper portion's raised bezel prevents it from touching the surface. Because of the case's sturdy back, it should withstand small drops. The on/off button is located at the back of the case, and the battery indicator features four bars.360-degree protection with a soft rubber head Camera protectionWith covered buttons, all ports are easily accessible.technology for advanced sync-throughSupport for all iOS versionsWith covered buttons, all ports are easily accessible.BluetoothOriginal Earbuds for your phonecharging while enjoying video, games, and music wherever you arePowerful 5000mAh Slim battery case gives your iPhone 7 Plus 8 Plus an additional 120% power, which translates to an additional 25 hours of talk time or 15 hours of internet browsing if you use this charging case.

The cover is as light as it can be on its own, but when the phone is added, it becomes somewhat heavy. But you have to put up with that because of the advantages it offers.With this case, my youngest son won't have to worry about his phone running out of battery again. Very highly advised

You need Adobe Flash Player to view this video.Download Flash Player.For heavy phone users like myself, the best battery pack. It's durable and gives me four whole phone charges. Before using this one, I tried a comparable product, and it ceased working after only a week. This product has not only lasted a long time, but it also lasts a long time before needing to be recharged.Excellent for travel and on the go. Definitely advisable!



Swaller Battery Case for iPhone 8 Plus/7 Plus, 5500mAh Slim Portable Charger Case Extend 150% Battery Life, Protective Backup Charging Case Compatible with iPhone 8 Plus/7 Plus (Black) Review:


My iPhone 6s Plus's original battery is getting old. I usually need a charging cord, power bank, or 120 volt charger because the phone battery does not last very long after noon. Since buying the Battery Case, I can leave the extra charging equipment at home and still have enough battery for the entire day.I adore not having to find an outlet or my power bank in order to get on with my day. By pressing the button on the rear of the battery case, I can quickly recharge my battery when I'm out and about. Just remember to hold the button down for three seconds to initiate charging. By briefly pressing the button, the led indicator displays the current charge percentage. One lead equals 25%, two equals 50%, three equals 75%, and four is a complete charge of 100%.This Battery Case should have been bought months ago. In terms of my iPhone, it greatly simplifies my day. If I were to drop my iPhone, it should be protected by the case, which seems to be well made.The installation is quite simple. There are just two parts. an expanded bottom and a condensed top. Slide the iPhone into the Battery Case after separating them, then secure the top section. The iPhone is quite simple to install or delete. When the lightning wire is connected, both the iPhone and the Battery Case are charged concurrently. There is no requirement for separate device charging.I'm happy with it and would suggest the iPhone Battery Case.



ZEROLEMON iPhone 11 Pro Max Battery Case, Wireless Charge + Headphone Support 5000mAh SlimJuicer Portable Protective Case, Compatible with iPhone 11 Pro Max 6.5”/iPhone Xs Max 6.5” Review:


This battery case feels good in the hand. This doesn't seem to slide out of my hands, but it isn't really "grippy" and is a little difficult to get into your pocket.It definitely adds to the size of a phone that is already large because this is a battery cover. The huge section measures 4 1/2" from the bottom to the start of the angle by little over 3 1/8" broad, and the case around the battery is 3/4" thick. These are merely ballpark figures to give you a place to start.Diagrams inside the case make it simple to insert your phone.I'll use this while I'm going camping and fishing for the day or going on a longer journey when I'll be spending a lot of time watching movies or listening to music.Regarding the wireless charging pad, all you have to do is be careful where you set it down. I occasionally missed the "place," but I never ran out of juice even when it wasn't charging.My truck has a built-in phone holder, but this case won't fit in there, so I won't put it in there for fear that it would fracture the holder. I simply leave it in the trunk since when it is plugged in, CarPlay launches, and I utilize that over Bluetooth. That was a part of the situation I predicted because I didn't think it would fit. I don't try to fit any other heavy duty, drop-rated cases I have into the holder either.All things considered, I'll utilize this when I need a longer battery or when traveling in a different car.I have communicated with ZeroLemon, and they have excellent customer service.



Battery Case for iPhone X/XS, 4000mAh Portable Protective Charging Case Extended Rechargeable Battery Pack Charger Case Compatible with iPhone X/XS / 10 (5.8 inch) (Black) Review:


You need Adobe Flash Player to view this video.Download Flash Player.really high quality stuff. This battery container has a whopping 4000 Amh capacity. The exterior of the case is made of silicon, while the interior protects the rear of the iPhone. Many battery covers make phones bulky, but this one is silicon, so my phone isn't as cumbersome to take around. Press the button on the case when the battery on your phone runs out, and you are ready to go. I'll definitely make another buy. Thanks



Swaller Battery Case for iPhone X/Xs/10, 4100mAh Ultra Slim Portable Protective Charging Case Extended Rechargeable Battery Pack for iPhone X/Xs (5.8 Inch) (Black) Review:


As a backup for my authorized Apple battery case, I purchased this. It appears that this battery case is noticeably superior. Additionally, this is less expensive than the genuine Apple battery case. Here are some details regarding this fantastic battery case that everyone should be aware of:1. This case provides at least one-third more power and lasts longer than the Apple certified case.2. Because it has pass-through charging, the phone will be charged first and the case second.3. In this situation, you can use the phone's charger. Most of the others on the list need a micro USB.4. The phone doesn't gain much weight with this case attached. Yes, it will thicken and add a little weight, but not significantly. In fact, the battery case helps me hold the phone more securely.The main negative is that charging requires pressing a button on the back, but in hindsight, that should also be a benefit since it will enable you to fully discharge the phone before you need it. Apple's case continuously recharges the case before drawing power from the phone's battery.Overall, I like this case better than the Apple case because it is tougher. The Apple case developed top-to-bottom tears after a few months.



Battery Case for iPhone 7/8, 4500mAh Portable Rechargeable Protective Charging Case Compatible with iPhone 7/8 (4.7 inch) Extended Battery Pack Charger Case (Black) Review:


I previously owned a case like this where the top half was secured with magnets. Even though I enjoy the color and sleek design of that case, I kept digging around in my luggage in search of that item. Although thicker because of the longer battery, this new and enhanced version is much superior. I can hold the phone more firmly because of the rubber texture. My hands are a little smaller than average, so the case's added thickness provides a more comfortable grip.Another great feature of these cases is that you can charge them with the same lightning cord that you use to charge your phone. The only thing this lacks—and I haven't used one that does—is the ability to charge both the cover and your phone simultaneously. If the case is on your phone, you are either using the battery to charge it or you are only charging the battery and not the phone.Only when I know I'm heading someplace where I might not be able to charge my phone do I miss the case. I usually don't completely empty the battery, so I can't vouch for how long it takes to recharge the phone.



U-good Battery Case for iPhone 7/8, 3200mAh Ultra Slim Lightweight Portable Protective Charging Case for iPhone 8/7(4.7 inch) Rechargeable Extended Battery Pack Charger Case,Support Headphone-Black Review:
